FILED OF DISCLOSURE

Embodiments of the present invention relate to the field of power management.

BACKGROUND OF THE DISCLOSURE

With popularization and development of computer technology, computer applications have spread across life and various industries. Under the popular use of computers, especially under the trend of environment sustainability, research in the field of computer power management has gradually increased. For example, there is always a need to conveniently switch a computer to standby mode whenever a user leaves the computer.

In response to this need, there are provided some traditional power management techniques. However, for an enterprise or an organization consisting of multiple clients, these traditional may in general fail because:

(1) The power management of an individual computer is typically solo managed that lacks of consistent tools and consensus standards. For example, the power management tools are variable from system to system, and the power policies usually depend on personal preference. One policy may be set to turn off monitor after 5 minutes computer idle; while another policy may be set to never turn off monitor regardless of the state of a computer.

(2) The short of a mechanism to monitor, measure and track energy consuming/saving in a centralized manner causes difficulties to statistics, reporting, recognizing and data analytics.

SUMMARY OF THE DISCLOSURE

To solve the above-described problems in the prior art, the present specification proposes a method, an apparatus and a computer program product for power management, and more specifically for power management in computer system.

As disclosed earlier, each of these separate modules may be combined into a single power management module.

FIG. 1 shows a block diagram of a power management system 100 according to one exemplary embodiment of the present invention. As shown in FIG. 1, power management system 100 according to one exemplary embodiment of the present invention may comprise a power management apparatus 110 and a power management client module 120. Power management client module 120 is installed on a client to manage power of the client. The power management mentioned in the present disclosure may be configured to save energy by reducing energy consumption when the computer is idle (for example, turning the computer to power saving mode or dormant mode). Those skilled in the art should understand each client has one power management client module 120 installed thereon; where there are a plurality of client computers, accordingly there are a plurality of power management client modules 120. Power management apparatus 110 is usually located on a stand-alone server to manage the plurality of power management client modules 120 in a centralized manner.

Power management apparatus 110 comprises a client management module 111 for configuring power management client module(s) 120 on one or more clients. As an example, power management apparatus 110 configuring power management client module 120 may comprise installing, managing or maintaining the power management client module(s) 120 on the one or more clients. For example, client management module 111 may push a relevant application to a client computer and remotely install the application on the client computer so as to create power management client module 120. In an implementation, power management client module 120 may integrate with other existing software management process and authentication/authorization control, for example install software on the client computer remotely. The type and version of an application may be adjusted on the basis of a target computer environment. The maintaining power management client module 120 may comprise operations like periodically updating power management client module 120. It may be observed that since power management client modules 120 on various client computers are under unified configuration and management of client management module 111, various power management client modules 120 have a good consistent power management policy.

Power management apparatus 110 further comprises a data collector module 112 for collecting, via power management client module(s) 120, power management related data of one or more user accounts on one or more clients. Optionally, the power management related data mentioned here includes, without limitation to, information on energy consumption of the client computer, and may vary on the basis of diverse application protocols of the power management client. For example, a Power Management Client that tracks the amount of energy that may be saved by manually switching a computer into low-energy model and querying to collect data about saved energy.

Power management apparatus 110 further comprises a repository module 113 for storing the collected data. Power management apparatus 110 may persist (store) collected data into repository module 113. Repository module 113 provides persisting capability to maintain the collected data or other related and/or required information. Interfaces are built to support necessary functions of storing, query, search and etc. Optionally but not necessarily, the collected data may be stored in correlation with a corresponding user account on a client. For example, where a plurality of users share one computer, the same client computer may contain a plurality of user accounts. At this point, there is a need to differentiate power management related data collected on this client comes from which user account, and data is stored in correlation with the corresponding user account.

It may be observed that power management apparatus 110 and system 120 according to one exemplary embodiment of the present disclosure enables an enterprise or another organization to maintain a consistent policy of power management crossing variable computers and thus achieve consistent power management.

Returning to FIG. 1, in an optional embodiment, power management apparatus 110 may further comprise at least one custom module 114. Custom module 114 may be defined by a user and provides user needed supplemental functions by making reference to data stored in repository module 113. Those skilled in the art should understand that custom module 114 is not essential and does not limit the scope of the present disclosure. As an example, custom module 114 may comprise one of more of: an analysis module 1041 for analyzing data stored in the repository module according to (e.g. user) needs; a statistics module 1042 for making/generating statistics on data stored in the repository module according to (e.g. user) needs; and a reporting module 1043 for presenting needed information (e.g. to the user). In addition, the custom module may also comprise a tracking module 1044 for tracking energy consumption etc.

Optionally, client management module 111 may additionally collect configuration information of a client via power management client module 120, such as software and hardware configuration information on CPU, Operating System, memory and the like. The information may also be stored in repository module 113 by client management module 111 for subsequent access. After additionally obtaining configuration information of the client, modules such as modules 1042 and 1043 may further measure the amount of energy saved by this client, thereby forming more quantized information.

With reference to FIG. 1, the process of tracking, in a unified manner, energy saving behavior of individual computers by using system 100 is described below.

1. Client management module 101 configures (e.g. Installs) power management client modules 120 on a plurality of client computers, which may be implemented using existing IT solutions like authentication, push software. Note that power management client module 120 may comprise various types or versions that are suitable for different computer platforms/OSs and may be changed to be applicable to various types of computers. In addition, power management client module 120 may further be designed such that by interacting with it (e.g., single click a button), a user may immediately switch the computer into low-energy model.

2. The user interacts with power management client module 120, for example by click of a button, to switch the computer to low-energy model whenever he/she thinks it is necessary.

3. Data collector module 102 interacts with power management client module 120 to collect client data, such as how often a certain user on the client switches to low-energy model actively; how long the computer is kept in low-energy model; etc. Alternatively, client management module 101 may also interact with power management client module 120 to collect the client's configuration information, such as software and hardware configuration information on CPU, Operating System and memory.

4. All collected data or information may be correlated with other metadata optionally. The metadata comprises user information or user account information and may be persisted into repository module 113.

5. Subsequently, some custom modules 114 provide more advanced service by consuming data stored in repository module 113. For example, statistics module 1043 is able to determine which user performs power management most actively among all users for a given client or for a group of clients or in general amongst all the clients. Analysis module 1042 may analyze that amount of energy saved by the user on the client on the basis of the client's configuration information and power management related data. Reporting module 1041 may provide a graphical representation of the amounts of saved energy to the user in a presentable form as desired.

That is, by the above various exemplary implementations of the present disclosure, not only unified power management of a plurality of clients is enabled, but also power management by various users may be learned by processing information like power management data collected from various clients. Thereby, an incentive may be offered to a user performing power management, and/or power management policies may be adjusted in a unified manner for achieving superior power management, etc.

It should be noted here that each of the separate modules described above may be advantageously combined into a single power management module and the power management module can collectively perform the tasks associated to each of the individual modules in a desired order or predefined order to achieve the end result of better power management.
